This page highlights four applications that use fiber optic cable: aviation, factory, medical, and shipboard. In the case of a military Airborne Warning and Control System (AWACS) aircraft, there are several benefits to using fiber optic cable: EMI noise immunity to transmitted radar signals, no radiated signals from the cable to interfere with the other systems on the aircraft, and lower overall weight which transfers to extended flight time. Commercial aircraft also employ fiber optics for their In-Flight Entertainment (IFE) systems. The fiber runs from the media server to the display in each seatback instead of having Ethernet hubs in every seat row and then running cable to the seat display. The use of fiber optics in the IFE reduces the hardware cost and total solution weight. Factory automation is the second application highlighted. Many industrial manufacturing facilities have large motors that produce large magnetic fields and electrical noises. The EMI noise immunity of fiber optics is ideal for these sites. In addition, many factories are large facilities that benefit from the additional distances that are allowed by using fiber optic cabling between machines and centralized computers. Medical also has the requirements for data delivery near equipment that generates large electro-magnetic fields which can interfere with data transmission over CAT 5 Ethernet. The last category is naval applications. The US Navy is outfitting ships and submarines with fiber optic networks for the main communications medium. Fiber optic cable allows for higher data bandwidth, immunity to EMI, and significant weight savings. An example of the use of fiber optics on a Navy ship is the Gerald R. Ford (CVN 78) that will contain over 4 million feet of fiber optic cable.
